Curvature-induced electroweak symmetry breaking and phase transition of a Higgs-portal dark scalar field
Andreas Mantziris
This overview of the study arXiv:2407.18845, regarding the possibility of generating gravitational waves from a curvature-induced phase transition of a non-minimally coupled scalar…
Gravitational waves from a curvature-induced phase transition of a Higgs-portal dark matter sector
Andreas Mantziris, Orfeu Bertolami
The study of interactions between dark matter and the Higgs field opens an exciting connection between cosmology and particle physics, since such scenarios can impact the features…
From Hubble to Bubble
Maciej Kierkla, Giorgio Laverda, Marek Lewicki +4
The detection of a stochastic Gravitational Wave (GW) background sourced by a cosmological phase transition would allow us to see the early Universe from a completely new perspecti…
Higgs vacuum metastability in gravity
Andreas Mantziris
Experimental data suggest that the Higgs potential has a lower ground state at high field values. Consequently, decaying from the electroweak to the true vacuum nucleates bubbles t…
Ending inflation with a bang: Higgs vacuum decay in gravity
Andreas Mantziris
According to the current experimental data, the Higgs vacuum appears to be metastable due to the development of a second lower ground state in its potential. Consequently, vacuum d…
Vacuum decay constraints on the Higgs curvature coupling from inflation
Andreas Mantziris, Tommi Markkanen, Arttu Rajantie
We derive lower bounds for the Higgs-curvature coupling from vacuum stability during inflation in three inflationary models: quadratic and quartic chaotic inflation, and Starobinsk…
